Mike used a whiteboard and erasable markers that were quickly drying out to show us how the Linux Filesystem Hierarchy Standard (FHS) is implemented in a typical operating system installation.
Mike had a handout (see below - click on the documents to enlarge) that described what each componentincludes and whether it is a shared directory. He included which ones are configured for read only or read write status.
He showed us how the latest FHS would typically be structured on a client and on a server. There were many questions fielded during the presentation and a period of discussion after Mike finished.
